This particular article does not highlight specific school districts. However, I know that the Bethlehem Area and Reading City School Districts have both been involved with interest rate swaps. It involves betting on variations in interest rates. Reading School District at one point had to pay in over one million dollars on a lost bet, although they had previously made profits on it.
